Los Angeles (CNN) -- As a federal court prepares to rule on a challenge to Sirhan Sirhan's conviction in the Robert F. Kennedy assassination, a long overlooked witness to the murder is telling her story: She heard two guns firing during the 1968 shooting and authorities altered her account of the crime.

Nina Rhodes-Hughes wants the world to know that, despite what history says, Sirhan was not the only gunman firing shots when Kennedy was murdered a few feet away from her at a Los Angeles hotel.

"What has to come out is that there was another shooter to my right," Rhodes-Hughes said in an exclusive interview with CNN. "The truth has got to be told. No more cover-ups."

Her voice at times becoming emotional, Rhodes-Hughes described for CNN various details of the assassination, her long frustration with the official reporting of her account and her reasons for speaking out: "I think to assist me in healing -- although you're never 100% healed from that. But more important to bring justice."

Once upon a time a child was born in a place called the land of the free and the home of the brave. She was told that she was very, very lucky to be born in this land, the best country on earth. In school every morning, her entire class stood, placed their hands over their hearts, and solemnly recited a Pledge of Allegiance to her nation’s flag. After that the class sang a stirring song about the greatness of this land and its purple mountain’s majesty. The same songs were heard on Independence Day, and, as the music swelled to a crescendo, tears filled the child’s eyes with gratitude for being a citizen of such a wonderful land.

Four decades later, the assassinations of John F. Kennedy, Robert F. Kennedy and Martin Luther King Jr. will be dissected this weekend at Duquesne University.

"Making Sense of the Sixties," a three-day symposium starting Friday and hosted by the Cyril H. Wecht Institute of Forensic Science and Law, will examine theories of cover-ups and conspiracies surrounding the slayings as well as ripple effects still felt today.

"It's a pretty weighty thing for people to confront," said Isaac Farris Jr., King's nephew and CEO of The Martin Luther King Jr. Center for Nonviolent Social Change in Atlanta. "Who knows how their deaths impacted our trajectory? Who knows where our nation might have been? My God, we wiped out three of the greatest leaders of a generation."

Filmmaker Shane O'Sullivan isn't sure whom he should thank more for pumping up the publicity on his new documentary film "RFK Must Die," which is currently showing at the Pioneer Theater in New York and debuts tonight on TV's WNYC 25 as well as airings on the Documentary Channel.

Presidential candidate Hilary Clinton deserves a shout-out for awkwardly raising the spectre of Bobby Kennedy's assassination in relation to the presumptive Democratic nominee Barack Obama. "Oh absolutely," says O'Sullivan from London, where he is based with his wife, who works in Japanese television. But Emilio Estevez deserves even more credit.

"Maybe the film "Bobby" started to bring Bobby Kennedy back into the public eye," says O'Sullivan about that acclaimed 2006 drama Estevez wrote and directed about Kennedy's last day.

Amy Goodman made note of the 40th anniversary of the assassination of RFK today with a tribute that included a useful history of the life and times of RFK, but Goodman also parroted the establishment line that Sirhan Sirhan killed RFK. Following this statement, Goodman played a segment of an interview with Sirhan's brother, Munir. During the segment, Munir notes that Sirhan has no memory of what happened that night at the Ambassador Hotel, and never has been able to remember what happened that night. Goodman then talked to John Pilger on the telephone, and Pilger made the stunning admission that not only was he there that night 40 years ago, he heard multiple shots, says that the shots kept coming even after Sirhan had been wrestled to the ground, and he told this to the FBI. Something tells me that Pilger would strongly agree with the recently released acoustic evidence;

JOHN PILGER: ... Sirhan leapt up on a serving area, pointed a gun at him and fired. He was wrestled. Kennedy fell. He was wrestled to the ground, and then there were other shots.

There’s no question that there was another gunman, because one of the people who was hit, just grazed, was standing next to me, and that happened when Sirhan Sirhan had been wrestled to the ground. So that’s the interesting thing. There was another assassin or another several assassins. And then it was bedlam. And as you know, Kennedy died about twenty-four hours later.

AMY GOODMAN: John Pilger, what about Robert Kennedy’s views of Vietnam? Also, of course, your view is not the standard one, that there were other assassins.

I'm not even going to attempt to offer an explanation for Goodman's behavior here... there are no words...

"Let's hear it for you... and people like you... who want to hear the truth, and want the truth to come out, and are not gonna rest until it all comes out."

Just as surely as the American public, and the rest of the world, was not told the truth about the assassinations of JFK and MLK, so it is with RFK, Robert F. Kennedy. Now, 40 years later, new scientifically derived evidence has come to the fore in the form of digitial acoustic analysis. But even before this analysis was available, a host of anomalies arise from the events of that day, as well as the strange mental condition of Sirhan Sirhan, which may be the indication of a mind-controlled asset.

June 5, 2008, marks 40 years of disinformation about the death of RFK. To mark the occasion, here is another video from Ralph Cole's amazing collection. Cole is the powerhouse behind justicevision.org,* a great collection of video footage, that has captured some of the most important speakers on these recurring events of deception. 9/11 was far from the first, but if we work hard enough, maybe it will be the last. It's educational to know about the events that precede 9/11, to note the similarites, and learn from them. Because you can be sure that the perpetrators do.

This is video footage of Lawrence George Teeter (Larry), who was Sirhan's lawyer until his untimely death in 2005. Sirhan is now represented by William F. Pepper. The talk is titled, "CIA Interventions: The Role of the CIA & the LAPD in the RFK Assassination", recorded in California at the Sepulveda UU Church, 11/14/2000. (approx. 84 minutes)

Tomorrow (5-6-2008) COPA will live stream some of the speakers from their RFK conference, and we will attempt to mirror the live stream.

Host of Air America's Clout, Richard Greene, bravely hosts the author of Act of State, William Pepper, who represented James Earl Ray on behalf of the Martin Luther King family and is now representing RFK patsy Sirhan Sirhan.

Forty years after Democratic rising star Robert F. Kennedy was killed at a Los Angeles hotel during his presidential run, new evidence suggests the man serving a life sentence for his murder did not fire the shots that killed the charismatic senator.
